Genomic organization of SARS-CoV, where one third of the right part of the genome encodes nine accessory proteins (3a, 3b, 6, 7a, 7b, 8a, 8b and 9b). These are interspersed between genes encoding structural proteins (S, E, M, N). UTRs are flanking the RNA at both 5′ and 3′ ends. Capping represented by solid yellow and leader sequence indicated by L are at 5′-end. ORF, Open reading frame; UTR, Untranslated region (created with BioRender.com. Accessed on 28 July 2021).
